First light data from Parker Solar Probe’s WISPR instrument suite: the right side of this image -- from WISPR’s inner telescope -- has a 40-degree field of view, with its right edge 58.5 degrees from the Sun’s center; the bright object slightly to the right of the image's center is Jupiter; the left side of the image is from WISPR’s outer telescope, which has a 58-degree field of view and extends to about 160 degrees from the Sun; it shows the Milky Way, looking at the Galactic center; there is a parallax of about 13 degrees in the apparent position of the Sun as viewed from Earth and from Parker Solar Probe.

This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

The Reiner Gamma formation is a well known lunar swirl region, due to its nearside location. Swirls are described by curving, diffuse bright patterns, which are interspersed with darker lanes. These anomalous albedo patterns are associated with local magnetic anomalies of varying intensities; swirl complexes are often extensive and may stretch across thousands of kilometers, well beyond localized magnetic anomalies.

The figure on the left is a composite image produced by adding 48 different exposures from News Horizons’ Long Range Reconnaissance Imager, each with an exposure time of 29.967 seconds, taken on August 16, 2018. The predicted position of 2014 MU69 is at the center of the yellow box, and is indicated by the yellow crosshairs, just above and left of a nearby star that is approximately 17 times brighter than 2014 MU69. At right is a magnified view of the region in the yellow box, after subtraction of a background star field ‘template’ taken by LORRI in September 2017 before it could detect the object itself. 2014 MU69 is clearly detected in this star-subtracted image and is very close to where scientists predicted, indicating to the team that New Horizons is being targeted in the right direction. The many artifacts in the star-subtracted image are caused either by small mis-registrations between the new LORRI images and the template, or by intrinsic brightness variations of the stars. At the time of these observations, 2014 MU69 was 107 million miles (172 million km) from the New Horizons spacecraft and 4 billion miles (6.5 billion km) from the Sun.
